MACOMIC, OF CHICAGO, ILLINOIS, ASSIGNOR TO PATENT PRODUCT COR- PORATION OF CHICAGO, 0F WILMINGTON, DELAWARE, A CORPORATION OF DELA- WARE PATTERN BED FOR TYPECASTING MACHINES AND THE LIKE Application led December 415, 1928. Serial No. 326,179.

My invention relates to improvements in pattern beds such as are primarily adapted for use in line type casting machines, type settin and printing machines and the like. One o ject of my invention is to provide in combination with a pattern bed having a plurality of longitudinally ydisplaceable pattern pins, means for controlling the position of said pins, and means for returning them to the starting position. Other objects will appear from time to time in the specilication and claims.

My invention is illustrated more or less `diagrammatically in the accompanying draw- A is a frame, preferably provided at onev end with pivot pin A1. This frame is rigid and adapted to be mounted in any suitable way in a type casting machine or other apparatus. Contained within this frame are a plurality of interlocking slotted longitudinal cross bars A2 and transverse cross bars A3. These bars are interlocked to provide a series of pockets A4 in which aremounted for reciprocation one in each pocket, a pattern pin A5. Spring plates A6 are associated with these cross v ars, there being a pair of spring fingers in each pocket so that these springV plates hold the pattern pins yieldably in whatever position they are placed.

In Figure 2, it will be noted that the pattern bed is mounted on pins B. These pins project upwardly from a main frame B1 and there is associated with the pattern bed and located above what may be called a plunger carriage B2. This carriage has a plurality of l separate plungers B3. Means not here shown and forming no part of the present invention may be used to depress by means of any one of these plungers 3 anassociated or related pattern pin. Figure 3 shows that this has been done and the pattern pin A5 has projected below the pattern bed so that it may engage a stop B4 on a moving member which is to be stopped in predetermined position by the pattern pin. l v

The pattern pins are arranged across the bed in correlated groups, the opposed pins in groups being cut away as indicated at C. C1 C1 are a series of correcting bars extending across the bed. These bars are supported in either end in longitudinal frame members C2 C2 mounted for reciprocation in the direction of the axis 'of the pattern pins. This arrangement forms in effect a grid iron which may be moved up and down by means of a series of bell crank levers C3 having working arms C4 engaging the frame C2 and adapted to be rotated by means of a connecting rod C5 which extends along the machine and may bev moved longitudinally to cause vertical movement of the grid iron frame and of the pattern pins. It will be noted that when the bars C1 are in the lower position as shown in Figure 3, the .pattern pins are free to be forced down, their downward excursion being limited by the engagement of the head G with the bar C1. When it is desired to return the pins to the starting position either for the purpose of correcting an error or to set themachine up for another operation, the

parts are brought into the position shown in Figure 6the bell crank lever is rotated in a counterclockwise direction as shown in Figure 6 and each of the bars C1 is moved up carrying with it any lof the pattern pins which may have been depressed and bringing vall the pattern pins back to the upper posicannot be raised above a certain point be- I cause theyl engage the underside of the bars,

thus resulting in substantial accuracy of the position of the pattern pins at all times. The movement of the bars being always in the direction parallel with the pins, there is no bending or jamming of the pins and they vare free -to move under the influence of the interfere with the movement of the pattern pins except in so far as they are engaged by the horizontal surfaces vformed by the cut away portion of the top and bottom.

Whereas in the claims I have described the transverse members as a bar it will be understood that I wish this term to be interpreted with sufiicient breadth to cover any member of equivalent action. In general I wish the description and drawings herein to be understood as illustrative rather than as strictly limiting me to the'showing herein since many changes may be made in size, shape, number and disposition of parts without departing from the spirit of my invention.

I claim:

1. In a pattern bed, a pattern pin mounted for longitudinal displacement and recessed intermediate its ends, a bar extending. perpendicular to the pin lying within the recess, means for moving the bar transversely to longitudinally displace the pin.

2. In a pattern bed, a pattern pin mounted for longitudinal displacement and recessed intermediate its ends to provide two opposed transverse surfaces, a bar extending transversely of the pin lying within the recess, means for moving the bar transversely to bring it into contact selectively with one or other of the transverse surfaces to longitudinally displace the pin.

3. In a pattern bed, a pattern pin mounted for longitudinal displacement, projecting at either end beyond the bed, recessed intermediate its ends at one -side of the bed, a bar extending across the bed at one side thereof lying within the recess, means for moving the bar transversely to longitudinally displace the pin.

4. In a pattern bed, a pattern pin mounted for longitudinal displacement, projecting at either end beyond the bed, recessed intermediate its ends at one side of the bed to provide two opposed transverse surfaces, a bar extending across the bed at one side thereof lying within the recess, means for moving the bar transversely to cause it selectively to engage one or other of the transverse surfaces to longitudinally displace the pin.

5. In a pattern bed, a pair of pattern pins mounted for longitudinal displacement and f vide two opposed transverse surfaces, a bar lying within said recesses, means for moving it transversely to bring it selectively into engagement with one or other of the transverse surfaces to longitudinally displace the pins.

7. In a pattern bed, a pair of pattern pins mounted for longitudinal displacement, projecting at one end beyond the bed, recessed in opposition to one 'side of the bed, a bar extending across the bed at yone side thereof, lying within said recesses and means for moving it transversely to longitudinally displace the pins.

8. In a pattern bed, a pair of pattern pins mounted for longitudinal displacement projecting at one end beyond the bed, recessed in opposition to provide two opposed transverse surfaces at one side of the bed, a bar extending across the bed at one side thereof lying within said recesses, means for moving the bar transversely to cause it to selectively engage one or other of the transverse surfaces to longitudinally displace the pins.

9. In a pattern bed, a pattern pin mounted for longitudinal displacement and recessed intermediate its ends, a bar extending transversely of the pin lying within the recess, means for moving the bar transversely to longitudinally displace -the pin and guide means in the pattern bed for the bar to maintain it normally out of contact with the pin.

l0. A pattern bed comprising a plurality of interlocking cross members forming separate pockets, pattern pins slidable within said pockets and recessed intermediate their ends,'a bar extending transversely of the pins located within said recesses, projections on some of said cross members in engagement with and forming guides for the bar to constrain it to movement parallel with the pins and means for moving the bar transversely to displace the pins.

11. In a pattern bed, a plurality of pattern pins mounted for longitudinal displacement, each pin having a transverse surface, a plurality of bars extending across the bed in opposition to said 'transverse surfaces, a frame supporting said bars and means for moving the frame toward and from the bed to bring it into and out of engagementwith said transverse surfaces.

l2. In a pattern bed, a plurality of pattern pins recessed to provide opposed transverse surfaces, a plurality of bars lying within said recesses, a frame supporting said bars, means for moving it toward and from the bed to bring the bars selectively into engagement with opposed transverse surfaces to move the pins toward and from the bed.
